Demo
    Diagram showing layers of a strain-sensing material. It includes a mechano-luminescent layer and a mechano-optoelectronic layer that creates current when exposed to light. Wires connect to measure voltage.
    A composite material piece with internal electronic circuitry is displayed on a metal workbench.
    This aerostructures test wing and setup are similar to those that will test the mechano-luminescent-optoelectronic composite at NASA’s Armstrong Flight Research Center. The wiring is attached to strain sensors and accelerometers.
    A close-up view of a tensile testing machine in a laboratory setting, with a sample material secured between its grips and connected to a measuring device via wires.
    An MLO composite sample is mounted in the strain test setup, where researchers apply tension to the composite, pulling on the ends of the sample in a load frame, and then measure the electric current and voltage produced by the composite.
